Standardize scripts

[Copilot]

This addresses the request to verify that copilot/standardize-scripts-format is behavior-preserving: run the modified scripts and confirm they produce the same on-disk results as master.
The outcome is parity: no branch-vs-master output drift was found for the modified synchronization scripts.

• Scope

  • Compared all modified scripts/*.sh files against master (16 modified files total).
  • Executed the runnable subset (scripts/synchronize-*.sh, 14 scripts) and compared filesystem deltas for each run.

• Environment parity adjustments (non-repo)

  • Installed missing Python dependency required by Istio flow:
    • ruamel.yaml
  • Used isolated temporary worktrees to avoid mutating the checked-out repository.

• Result

  • Script execution matrix shows branch_exit == master_exit and branch_changed == master_changed for every runnable modified script.
  • Equivalent output sets and content hashes across branch and master for all compared runs.

COMPACT_MATRIX
script|branch_exit|master_exit|branch_changed|master_changed|equivalent
scripts/synchronize-cert-manager-manifests.sh|0|0|3|3|yes
...
scripts/synchronize-training-operator-manifests.sh|0|0|3|3|yes

SUMMARY
all_scripts_success=True
all_outputs_equivalent=True

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Pull request overview

This PR standardizes the Kubeflow manifests synchronization shell scripts to use shared helpers (library.sh) consistently, while aiming to keep on-disk output behavior identical to master.

Changes:

• Simplifies and normalizes synchronization script structure (variable naming, whitespace, and shared helper usage).
• Replaces per-script copy/README/commit logic with copy_manifests, update_readme, and a unified commit_changes call pattern.
• Refactors a few scripts to reduce inline sed/copy logic in favor of common library functions.

[Copilot]

create_branch uses if [ $(git branch --list "$branch") ]; then ..., which can emit a test error when the branch does not exist because the command substitution expands to an empty string (resulting in [ ]). Use a string test with proper quoting (e.g., if [[ -n $(git branch --list "$branch") ]]; then) or a command that directly checks existence (git show-ref --verify --quiet "refs/heads/$branch").

[Copilot]

The README link replacement patterns for the CRUD web apps use crud-web-applications/..., but the root README.md currently references components/crud-web-apps/... (no "-applications"). As a result, these update_readme calls will not update the corresponding rows when COMMIT changes. Consider broadening the match (handle both paths) or aligning the patterns to the current README paths so the version table stays in sync.
